Serial No. 616,181.

To all whom it may concern Be it known that I, JOHN M. Conner, a citizen of the United States, residing at Raum, in the county of Pope and State of Illinois, have invented a new and useful Vise, of which the following is a specification.

This invention relates to an improvement in vises.

The primary object of said invention is to provide a vise which will be simple in construction, the construction being such that the same may be readily positioned on the ordinary work bench without materially altering the construction of said bench.

A further object of the invention is to provide a jaw-closing means which will coact with the end portion of one of the jaw members in such a manner as to close said jaw member.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without depart-ing from the spirit of the invention.

In the drawings :-Figure 1 is a front elevation of the vise positioned on a work bench, Fig. 2 is a side elevation partly in section, Fig. 3 is a section taken on the line 3-3 of Fig. 2; and Fig. 4 is a rear elevation partly in section.

In the drawings, 10 designates a work bench of the usual construction consisting of a plurality of supports on which is positioned the table 10. The vise is positioned adjacent one end of the table and consists of the rigid jaw member 11 which extends at an angle to the base support 12 of the bench, the end portion of the jaw extending within said base portion, the table being cut away in order that the jaw may extend above the same.

Arranged directly to the rear of the jaw 11 is a support 13, there being a brace 14 spacing the jaw and said support 13, said brace 14 being secured to the under face of the table 10. A second jaw 15 is supported adjacent the jaw 11, said jaw 15 being about one-half the length of the jaw 11 and being supported at a point below its center by arms 16 and 17 which are secured to the jaw 11, said arms being adjustable in order to space the jaw 15 from the jaw 11, a strap 18 extending transversely across said arms and the beam 14, said strap and its securing devices 19 forming a guide for the arms 16 and 17 permitting the adjustment of said arms relative to the stationary jaw; the stationary jaw being provided with an opening through which the pin 20 passes, said pin holding the arms against movement. The end portion of the jaw 15 is beveled, said beveled end portion being covered with a strap or wear plate 21, the end portions of which are secured to the sides of the The jaw 11 is provided with a vertically disposed slot 11 and extending through said slot is a treadle 22, said treadle being pivotally upheld by the support 13; the rear face of the aw 11 having secured thereto a rack 23 which is engaged by the beveled edge 24 of the treadle 22.

A lever 25 is pivotally supported within the slot 11 of the stationary jaw, a plurality of apertures being arranged in said lever in order that its fulcrum may be shifted. The end portion of this lever terminates in arms 26 which support a roller 27, said roller being normally in contact with the strap 21 upon the beveled end of the jaw 15. The lever 25 is connected to the treadle 22 by a plurality of links 31 which as the treadle is depressed draw the end portion 25 of the lever 25 downward forcing the roller 27 across the beveled end of the jaw 15, thus forcing the lower portion of the aw outward and its upper contacting portion inward, securely gripping the material 33; the lower portion of the jaw 15 being normally drawn toward the base of the jaw 11 by a coiled spring 34, which is secured to the support 13 and is connected to the jaw 15 at a point below its pivot. Thus it will be seen that the action of the spring 34 overcomes the tendency of the lever 25 to draw the upper portions of the jaws together, the vise in this way having its jaws normally open to receive the material to be clamped, the clamping being readily accomplished by depressing the treadle 22, said treadle being locked against upward movement by the rack 23 when the treadle has been depressed, the treadle being moved to one side when it is desired to release the same from said rack to open the jaws.

Thus it will be seen that a simple and ellicient vise is provided which may be economi cally manufactured and which may be readily positioned on the ordinary type of work bench without materially altering its construction, the locking of the jaws being easily and positively accomplished through the cooperation between the pivoted lever and the beveled end portion of the movable aw.

What is claimed is In a vise, a fixed jaw; an arm supported by the fixed jaw; a movable jaw located in front of the fixed jaw and pivotally connected below its center with the arm, the movable jaw having its lower end face beveled; a treadle; a fulcrum for the treadle, independent of both jaws and located to the rear of the fixed jaw; a lever fulcrumed intermediate of its ends in the fixed jaw;

and an anti-friction element upon the forward end of the lever, engaging the beveled end of the movable jaw to thrust the upper ends of the jaws together; a link located to the rear of the fixed jaw and pivotally connected with the treadle and with the lever; a retractile spring connected with the movable jaw, below the pivotal mounting of the pivotal j aw; and means for securing one end of the spring.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
